PAPER-CARRIAGE FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 432,297, dated July 15,1890.

Application filed July 5, 1889.

construction of parts comprising the papercarriage, to economize in thecost of its construction, and of repairs to or replacement of any of itsparts, and to make the same more efficient and effect greater rapidityof writing.

My invention accordingly consists of the combinations, constructions,and arrangements of parts, as hereinafter more particularly described inthe specification, and

pointed out in the claims, reference being had to the accompanyingdrawings, wherein Figure 1- represents an elevation, partly sectional,.of a type-writing machine paperholding carriage embodying myimprovements. Fig. 2 represents an end view, partly in section, of same,looking in the direction of arrow 1, Fig. 1. Fig. 3 is a like view ofsaid end, showing part of pawl-and-ratchet mechanism on the shaft of theupper roller at said end removed, and also showing pressure-fingers forsaid roller. Fig. 4 is an end view, partly in section, of the oppositeend of the carriage. Fig. 5 is a plan of part of the base-plate of thecarriage, showing adj ustable stop-finger for limiting the returnmovement of the carriage; and Fig. 6 is an elevation of the base-plateof the carriage and the machine-bed, the latter being in dotted lines,with roller-supports on said machine-bed for the carriage.

A represents the paper-carriage, consisting of a bottom plate or basedand end bearings, standards, or supports B and C for the paperearryingrollers D and E. The bottom plate a has preferably dovetail or otherlike edges a supported and sliding in a correspondingly-formed guidewaya in the frame A of Serial No. 316,589. (No model.)

the machine. The guideway a is open from end to end of the machinetransversely, and

the carriage is considerably longer than the machine A is wide, asshown-more plainly in Fig. l, and has suitably formed and arrangedfeeding-racks (L3 on the under side of the bottom plate, as illustrated,or otherwise,'as desired. The paper-carriage is normally not inengagement with its actuating feeding-pawls or mechanism, or is normallyindependent of the same, and is only in engagement therewith when a keyor finger-lever is depressed, as fully set forth in anotherpendingapplication of an even date herewith, Serial No. 316,591, and thereforesaid feeding mechanism is not shown in the drawings, as it forms no partof my present invention, as any desired form of feeding mechanism maybeused in connection with the independent carriage A. The latter beingnormally disconnected from its feeding-pawls, it is normally free toslide or can be adjusted longitudinally in either direction, as desired,to suit the work to be done without necessitatingmanual disengagement ofits feeding mechanism, and as it slides in an open end guideway (t thecarriage can be at once removed from the machine and another ofdifferent length substituted for printing on extended widths of paper,and this avoids the necessity of making specially-large machines forlarge or extended lengths of paper-carriages.

To give additional support for extended lengths of carriages, fixed sidearms or brackets a a on the machinebed A, having suitable guideways orsupports for the carriage, may be used, as shown in Fig. 1, or hinged orpivoted arms or brackets a", with end supporting-rollers a, may beemployed, as shown in Fig. 6. The advantage of using the hinged orpivoted brackets a is that when long car'- riages are not used and whenthe machine is packed for transportation or other purposes the bracketsa can be swung around to the side of the machine to reduce itstransverse width, as indicated to the right of Fig. 6.

The roller E maybe journaled or mounted in the carriage-standards l3 andC, as desired. The upper roller D is mounted in standards B and C so asto be bodily separable throughout its entire length from the roller E tofacilitate the insertion of the paper, especially when manifolding,between said rollers. To this end I make the standard 0 in sections, theupper sect-ion 0 being pivoted or hinged to the lower section, asindicated at c, and in this pivoted section is journaled the end (1 ofshaft (1 of roller D. The opposite end (1 of said shaft (1' is journaledin an elongated slot 1), having an open upper end in standard B, saidshaft end (Z being held to its bearing by a pawl l), suitably pivoted tothe standard B, and having a spring b which acts to impart to pawl b adownward pressure upon the shaft end (1 By providing the pawlb with asuitable handle or lug b, by means of which it can be manuallydisengaged from shaft end (Z the roller D can be raised or swunon thepivotal connection of section 0 of standard G to separate it from rollerE, as indicated by dotted lines a, Fig. 1, for ready insertion of thepaper between the rollers D and E, which is especially advantageous whenmanifolding a number of sheets or copies, as the latter can be instantlyinserted between the rollers without liability of slipping upon eachother.

Upon the end (I of shaft (Z,at its outer end, is a knob or handle f formanually turning the roller D in either direction, as desired. Back ofsaid knob or handle is a ratchetwheel f, having a check-spring pawl fsecured to standard-section c and an actuating-pawl g, pivoted at g to alever G, loosely mounted on shaft end (Z. Said pawl g is pro vided witha handle or lug g for manually engaging said pawl with the ratchet-wheelf for rotating the roller D to turn the same in order to feed the paperfor the lines of printing or writing. Said pawl g is so pivoted that itis normally out of engagement with the ratchet-wheel f, as more plainlyindicated in Fig. 2, so that it will not interfere with the rotation ofthe roller 1) when a movement of knob or handlef is made.

The lever G has at its upper end a screw 9 the end of which abutsagainst the standard -section extension 0 being maintaiued normally insuch impingement by a spring acting against a toe g at the lower end ofsaid lever. (See more plainly Fig. 3.) The screw limits the movement oradjustment of lever G in one direction, and its toe g limits themovement of said lever in the opposite direction. By adjusting the screwg the extent of movement of the lever G is varied to correspondinglyvary the extent of movement of the pawl g and the ratchetwheel f toincrease or decrease the turning movement of roller D and in turn thefeed of the paper for the distance between the lines.

To rotate the roller-D by the pawl g, the operator presses against itsknob or handle 9 the first movement of which engages the pawl g with theratchet-wheelf', after which the lever G and pawl 9 move together torotate the ratchet-wheel and in turn the roller D, the

terminal movement of said parts being limited by the lever-toe gabutting against a shoulder or ledge on standard-section c. As soon asthe pressure is released from the pawl g the reaction of spring returnsthe lever G and pawl g to their normal positions. WVhen in thisposition, the pawl g is free from the ratchet-wheelf, and by thenturning the knob or handle f on shaft d the roller D can be rotated ineither direction to any extent, as desired, independent of its feedingmove ment for spacing between the lines, such independent rotation beingespecially desirable for underscoring, canceling, and other likepurposes, as fully set forth and claimed in my other aforesaid pendingapplication of even date herewith, Serial No. 316,591. It will be notedthat as the rotary-feeding mechanism for the roller D is located ormounted on its shaft and standardsection c all of said parts move withthe roller when it is raised or separated from the roller E.

It is obvious that the novel features of construction of the separableroller D, as well as those of the rotary-feeding mechanism, areapplicable to different forms of paper-holding carriages havingpresser-rollers.

If it is desired to limit the return slidingmovement of the carriage,this may be done by using an adjustable stop II, sliding in openings instandard or standards B and G and held in its adjusted position by aset-screw h, the end of said rod being bent, as indicated at h, andadjusted to strike against the end. of the way or guide a", as indicatedin Fig. 5, to stop the return movement of the carriage; but, if desired,any other suitable stopping device may be employed, as I do not in thisapplication claim such stopping mechanism.

\Vhat I claim is 1. In a type-writer paper-carriage, the combination ofthe fixed bracket B, having at its top an open end bearing, thesectionalbracket 0, having lower fixed part and upper swinging part, thelower roller E, journaled in the fixed bracket B and in the fixed partof the sectional bracket 0, roller D, having one end journaled in theswinging part of bracket 0 and its other end in the open bearing ofbracket B, and retaining device for the jour-- nal of roller D on saidopen bearing, substantially as set forth.

2. In a typewriter paper-carriage, the standard B, having an open endslotted bearing, a movable pawl in said slotted bearing, the sectionalstandard (3, and roller D, having one end journaled in said sectionalstandard 0 and the other in said slotted bearing, substantially as setforth.

3. In a paper-holding carriage, the combi nation of slotted bracket B,movable pawl in said slotted bracket, standard C, having hinged orpivoted section 0, and roller D, substantially as set forth.

4:. In a paper-holding carriage, the combi nation of .a hinged orpivoted bracket, a fixed bracket having an open bearing, a roller- ICCTIO

platen D, having one end journaled in the hinged bracket and the otherjournaled in the open bearing of the fixed bracket, and a retainingdevice in said fixed bracket for the end of the roller journaled in saidopen bearing, substantially as described.

5. In a type-Writer paper-carriage, the combination, with roller D andits shaft (1, of a ratchet wheel rigidly secured to said shaft, a leverjournaled concentrically on said shaft and having at one end a toe g andat the other end a set-screw 9 a feeding-pawl for said ratchet pivotedin said leverand normally out of engagement with the ratchet, andstandard C, having stops for said setscrew and toe for regulating theextent of said lever and paw], substantially as described.

G. In a type-writer paper-carriage, the com- 20 bination, with roller Dand its shaft (1, of a standard 0, having stops for said set-screw andtoe for regulating the step-by-step feed of said lever, and frame forroller D, and a feed-knob f, rigidly secured to the shaft of roller Dfor turning said roller independently of said step-by-step feedmechanism, substantially as set forth.
